High-steep slope plant cultivation method

Abstract

The invention discloses a high-steep slope plant cultivation method. 5-10cm thick ecological concrete is cast on a high-steep slope surface and prepared by the following steps: mixing and stirring gravels, cement, silica micro-powder or coal ash, water reducers, water, turfy soil and diammonium hydrogen phosphate according to the weight ratio of (1400-1800):(200-350):(20-50):(2-6):(40-90):(3-20):(0.5-5); laying grass knot nets on the slope surface, holding iron wires into U shapes, fixing the grass knot nets onto the ecological concrete, fixing plant seeds onto the ecological concrete by the iron wires, supplementing water and covering the slope surface with non-woven fabrics; removing the non-woven fabrics after germination, and applying fertilizers once every 5-7 days. Slope soil can be effectively fixed, ecological environments are improved, harm to plant roots and stems at the growth stage caused by rain wash can be effectively prevented, plant cultivation success rate is greatly increased, the vegetation coverage rate of a slope is increased, and desertification and water and soil loss can be prevented.

Description

technical field [0001] The invention relates to the technical field of ecological environment protection, in particular to a method for planting plants on high and steep slopes. Background technique [0002] The side slope is a slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. Slope greening is the focus and difficulty of expressway greening. At present, expressway greening generally follows the principles of urban landscaping. We don’t know the ecological environment, vegetation conditions, and plant species along the highway. We mainly use exotic plants, and there are monotonous and resistant tree species. Poor performance, high maintenance management costs, etc., especially semi-weathered rocky slopes, because of the thin and barren soil layer, difficult for plants to take root, and easy to be washed by rainwater, etc., there are great difficulties in greening. But existing slope planting plants, especially high and stee...

Slope greening is the focus and difficulty of expressway greening. At present, expressway greening generally follows the principles of urban landscaping. We don’t know the ecological environment, vegetation conditions, and plant species along the highway. We mainly use exotic plants, and there are monotonous and resistant tree species. Poor performance, high maintenance and management costs, especially semi-weathered rocky slopes, because of the thin and barren soil layer, difficult for plants to take root, and easy to be washed by rainwater, etc., there are great difficulties in greening

But existing slope plants, especially high and steep slopes, are easily washed by rainwater and grow unevenly, as shown in a method for greening exposed slopes with reeds as disclosed in the patent No. CN03139818.9

In addition, only reed-like grass grows on the slope, which is far from the surrounding natural vegetation, which reduces the greening effect
